chromeos: vboot: Adaptations for using a separate object out directory

$(obj) might be defined either as a relative or an absolute path. This, it has
    to be filtered out before adding $(top) to it (in case of an absolute path) when
    building vboot. It is then provided separately in CFLAGS (as an absolute path).

In addition, VB2_LIB inherits $(obj), so it might also already be an absolute
    path, and prefixing $(top) to it doesn't apply. Thus, the absolute path to it
    should be passed to the vboot make command.
